Your list of symptoms threw me off. I found it odd. But, then again, maybe it was intended to be humorous.
Schizophrenia is about an excess of dopamine and responding to "internal stimuli." Symptoms of schizophrenia are divided into two subtypes: positive and negative symptoms (not "good" and "bad," but rather symptoms that either cause an excess or absence of typical functioning).
For example, a positive symptom of schizophrenia may be laughing without an appropriate external cue to make the person laugh. A negative symptom might be catatonia. Positive symptoms are the things we typically think about when we think of schizophrenia such as auditory and visual hallucinations (e.g. if you hear funny voices, that may cause you to laugh).
Antipsychotic medications are designed to treat the positive symptoms and often do so successfully (or they at least cause a significant reduction of positive symptoms). Conversely, negative symptoms are basically untreated by antipsychotic medications and are typically seen as more debilitating.
Antipsychotics are split into two subtypes: typical and atypical antipsychotics. Typical antipsychotics were the first generation of antipsychotics (e.g. Haldol) while atypical antipsychotics (e.g. clozapine) are the 2nd generation of antipsychotics. While both subtypes primarily treat positive symptoms only, and while there is (generally) no difference in general efficacy of either generation of antipsychotics, the atypical antipsychotics are generally purported to be safer and have decreased levels of side effects such as tardive diskenesia (though they usually do not eliminate the side effects completely).
